Abstract
Die Erfindung betrifft ein Verfahren zur Präparation einer Besetzungsinversion in einem Quantensystem (Q) mittels Mehrpulsanregung, wobei ein Quantensystem (Q) umfassend wenigstens einen Quantenpunkt mit zwei orthogonalen Zuständen (/X>, /Y>), insbesondere die mit zueinander orthogonalen Polarisationen (P1, P2) optisch anregbar sind, mit einem ersten Laserpuls (L1) beleuchtet wird, welcher zur resonanten Anregung des ersten (/Y>) der zwei Zustände (/X>, /Y>) eingestellt wird und zeitlich nachfolgend mit einem zweiten Laserpuls (L2) beleuchtet wird, der zur resonanten Anregung des zweiten (/X>) der zwei Zustände (/X>, /Y>) eingestellt wird.
The invention relates to a process for the preparation of a population inversion in a quantum system (Q) by means of multi-pulse excitation, wherein a quantum system (Q) comprising at least one quantum dot with two orthogonal states (/ X> / Y>), particularly the (mutually orthogonal polarizations P1 , P2) are optically excitable, is illuminated with a first laser pulse (L1) which is (for resonant excitation of the first (/ Y>) of the two states of / X, / Y>) is set> and temporally below (with a second laser pulse of (for resonant excitation of the second (/ X>) of the two states of / X, / Y>) is set> L2) is illuminated.
